CHARLES SUMMERS BAYNTON, OF BIRMINGHAM, ENGLAND.

To all whom it may concern:

Be it known that 1, CHARLES SUMMERS BAYNTON, subject of the King ofGreat Britain, residing at Exchange Buildings, New street, Birmingham,England, have invented certain new and useful Improvements in Apparatusfor Washing Photographic Prints, Films, and such like, of which thefollowing is a specification, reference being had therein to theaccompanying drawings.

The invention relates to photographic print, film, or like washer of theperforated drum kind revolving within a tank holding washing liquid, andprovides the hereinafter described and claimed combination of partshaving for their primary object the prevention ofthe prints, films, orthe like sticking or becoming attached to the interior of the drum or toeach other.

The perforated drum is formed with corrugations so arranged that theprints can only touch the tops of the corrugations, and

i the washing liquid can travel along the depression between the saidcorrugations to prevent the prints from resting on the said tops. Oneend of the perforated drum out side the corrugations is closed by animperforate plate, and the opposite end, which is also provided with aperforated corrugated plate, is only partially closed, while at thissame end the perforated drum is provided with a water wheel having anopen middle part. The perforated drum revolves in-the liquid containeronly partially submerged. A supply of washing liquid, firstly, fills thepockets of the water wheel above the water level to slowly revolve thedrum, and then overflows into the liquid container at the partially openend of the drum.

The features aforesaid and hereinafter clearly stated in the claims areshown by the accompanying drawings using. the water from an ordinarypressure water tap. Figure 1 is a plan of the apparatus. 2 is alongitudinal vertical section.

is a transverse section on the dotted lines A semicircular crosssectionally as shown. This tank is mounted upon feet 0, and is providedwith an outside overflow for the washing liquid in the form of avertical passage a, which communicates with the bottom of the tank onlyby the opening (l the liquid overflowing at the upper end (i so that theheight of said upper end decides the height of the constantly changingwashing liquid within the tank. The opening d is an outlet from aportion d of the bottom of the tank inclosed' by a freely perforatedcovering d c e are upwardly-opening bearing pieces oppositely providedinternally of the tank at the ends to support the combined revolublecontainer and water wheel, hereinafter particularly described.

f is the print containing drum, and g is to revolve within the bearingpieces e e, the

revoluble element simply dropping into position Within the tank, and,therefore, being easily removable for putting in and taking out theprints. The print container 7' is formed by a freely perforated shell fwhich is longitudinally corrugated from end to end thereof, as clearlyshown in Fig. 3, wherein f indicates the corrugations proper and f thedepressions therebetween. said shell at and near the ends 1' and j ofthe container being rigidly attached to metal bands f i carried by saidends'to make effective attachment of the shell to the ends. A door Zforms part of the shell and is hinged at Z? to a bar Z extending betweenthe bands f f, the opening edge Z of this door fastening to a bar Z verysimilar in construction and application to the bar I. The door has aframe 1 paneled at l with freely perforated metal having corrugations ofthe same kind as the greater part of the shell, so that when the door isclosed the interior surface of the shell is almost wholly of perforatedcorrugated metal, or other suitable material.- m is the fasteningbetween the opening edge 1* of the door frame andrthe bar Z. That end iof the container to which the water wheel 9 is applied is formed at thecenter with'an opening 2' while the end 7' is im erforate or closed..Eaohend is lined wit a perforated disk n of metal or other suitablematerial provided with corrugations similar to .those on the shell 7,-the corrugations across said ends being parallel with each other,although they may be in ring formations on said disksgwhich; :are alwaysfixed parts of -,the print container and revolve at a1l:timestherewith,,

The water wheel g,;th e pockets. of which are shown at i9 3: is of anopen construction inward ofsaid pockets for the full area of the openingi as shown at 9.3, the washing liquid in the actionof the apparatuscirculating freely, through this open metal part of the, water wheelandthrough the opening 2' into the container, the trunnion h at this end oftherevoluble part of the apparatus being rigidly carried by a bar 71,extending from the bottoms ofthe pockets 9,- diametrically across theopen metal part g. y The pockets 9 of the water wheel are formed so asnot to pick; up any water on oneside, and so that two or three of themcombine withthe water they contain to ef- I feet the rotation .of thecontainer, such pockets being operative above the washing liquid level,whichis indicated by the dotted lines y Figs. 3,and 4.

p :0 indicates an. adjusted nozzle carried by the tank and fed from apressure water tap or other supply,,same being provided withxa unionconnection,- at so that the correct position of its outlet end ar" canbe determined to fill the requisite pockets on one side of the center'to cause a continuous and steady revolution of the print containerwithin the tank, the gradual filling of the pockets with water combiningwith the resistance to the too-free rotation due to the and circulatescentrally through the open end i of the container and travels to theclosed, other end of said container, and is'by said end returned to flowin the opposite direction.

By arranging the corrugations longitudinally of the walls of thecontainer, the revolution of the latter will cause the sides of thecorrugations to exert a beating action on the water which forces thesame to pass through the perforations and thus-dislodge any prints thatmight have become momentarily attached to the container walls.

Having now described my invention, what I claim and desire to secure byLetters Patent is f 1. In a washing apparatus, the combination of aliquid container, a drum supported to revolve within said container andmade of freely perforated, corrugated metal with the corrugations of thecylindrical wall arranged longitudinally of the drum, and means forrevolving the drum in said container, substantially as described.

2. In a washing apparatus, the combination of a liquidcontainer; a drumsupported to revolve within said container and constructed ofperforated, corrugated metal, one end of said drum being closed, and theother end thereof provided with an opening; a water wheel connected tothe-seconds named end of said drum; and means for supplying washingliquid to said water wheel, to revolve said drum and afterward overflowinto the container.

3. In a washing apparatus, the combination of a liquid container; a drumsupported to revolve within said container and con-- structed ofperforated, corrugated metal; a water wheel connected to one end of saiddrum; and means for supplying liquid to said water wheel, to revolvesaid drum.

4. Ina washing apparatus, the combination of a liquid container; a drumsupported to revolve within said container and only partially submergedtherein, said drum being constructed of freely-perforated, corrugatedmetal, with thecorrugations of the cylindrical wall arrangedlongitudinally of the drum, one end of said drum being closed, and theother end thereof provided with an opening; a Water wheel connected tothe second-named end of said drum; andmeans for supplying washing liquidto said water wheel, to revolve said drum and afterward overflow intothe container.

5. In a washing apparatus, the combination of a liquid container; a drumsupported to revolve withinsaid container and con-- structed ofperforated, corrugated metal, with the corrugations of the cylindricalwall arranged longitudinally of the drum; a water wheel connected to one.end of said drum; and means for supplying liquid to said water wheel,to revolve said drum.

6. In a washing apparatus, the combination ofeliquid container; afirumsupported means for directing a. supply of liquid to revolve within saidcontainer and con against said water wheel, to revolve said structed ofperforated, corrugated metal, drum. one end of said drum being closedexternally In testimony whereof I aifix my signature 5 o; theco'ralgatifins, and the other end thfirei in the presence of two'Witnesses.
